ABSTRACT OF THE DISCLOSURE A device for interconnecting turbine blades com- prises a pair of projections extending towards each other from the opposing sides of the tips of adjacent blades, having an inclined inward surface, and having a radially extending perforation. A cover piece has a pair of inclined outward surfaces conforming to the inward surfaces of the projections. The cover piece also has lugs extending through the perforations in the projections. One of the lugs has its end peened to form an overhang for abutting the projection. The perforation of the opposite projection is elongated to permit untwist of the turbine blades. The interconnecting device according to the present invention has an improved capability of permitting untwist- ing deformation and of damping the vibration.
